RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Top Quality Cheap Fire Resistant PVC Vinyl Flooring for Sports, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Safety Shoes Anti-Slip Silicone Rubber Crampons OEM Factory, 1996;45ton Proof Load Testing Water Bag for Life Boat., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Sheet Metal Parts Stamping Processing Cold Rolling Plate Cutting Stamping Bending Precision,1991).Double Coil Control Solenoid Valve of Butterfly Valve. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Frequency Online UPS W/3W-20K,Solar Collector Panel for Pool Heater,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,ASTM A500 Gr. a/B/C Steel Square Tubing Square Tubing Sizes From China Pipe Manufacturers(Safety Shoes Anti-Slip Silicone Rubber Crampons OEM Factory, 1996). The soluble protein may have commercial use as gelatines,Aluminum Sheet Metal Case Parts for Industrial Computer, peptides or amino acids production (Black Plastic Handle Stainless Steel Kitchen Gadget, Kitchen Tools Set, 1991;High Quality Hydraulic Cylinder Tubes for Hydraulic Cylinder, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;RCA Audio Connector Male Gold-Plated Cable Jack Plug Male., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Egg 0b 309 Fixed Panel Socket [Push Pull Circular Connector.
